Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the tread pattern repeats uniformly throughout the outer surface and shoulder circumference of the tire tread, the opposite side perspective view being identical thereto; and,

FIG. 2 is a enlarged fragmentary front elevation view of the tire tread thereof.

The broken line disclosure of the sidewall and inner bead of the tire is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
